Retrieve the content of the log file associated with worker 'ord'.

If 'ord' is "*" (default), all the workers are retrieved. If 'all' is true, the whole files are retrieved; else a max of fgMaxTransferSize (about 1000 lines) per file is read, starting from the end (i.e. the last ~1000 lines). The received buffer is added to the file fname, if the latter is defined. If opt == TProofLog::kGrep only the lines containing 'pattern' are retrieved (remote grep functionality); to filter out a pattern 'pat' use pattern = "-v pat". Return 0 on success, -1 in case of any error.
